The City Library and Archives Office utilizes its website to deliver information and services. However, its development has not yet considered user comfort and an adequate User Interface (UI) design, which reduces user satisfaction. This study aims to identify the elements that influence interface design and determine the reference specimen for UI design recommendations. The research employs the Kansei Engineering (KE) approach to connect user emotions with design elements. Data were collected through a questionnaire using 28 Kansei words to analyze five website specimens, involving 50 respondents. The analysis was conducted using Principal Component Analysis (PCA), Factor Analysis, and Partial Least Squares (PLS). The results indicate that the Kansei word "beautiful" has a dominant influence on user emotions (value: 0.995). The City Library and Archives Office of Riau’s website was identified as the most suitable reference specimen for the expected design concept. Design recommendations were formulated based on the PLS analysis, covering elements such as layout and color to ensure an optimal design. This study highlights the importance of emotional aspects in UI design to enhance user satisfaction and improve the effectiveness of information delivery.Keywords - Kansei Engineering, Multivariate Analysis, Partial Least Square, User Interface, Website.

Working in hot and humid environments poses significant challenges to thermoregulation and potentially affects performance and health. Strategies for mitigating heat stress are critical for workers exposed to high thermal loads. This study investigated practical cooling strategies, that is, phase-change vest (PCV) cooling and crushed ice (ICE) ingestion, before a physical activity in a hot and humid environment to alleviate heat strain. Two experiments were conducted to evaluate the efficacy of the cooling methods: the first experiment involved participants wearing a PCV for precooling, and the second experiment involved participants consuming an ICE (7.5 g/kg body mass) before exercising under the same conditions. Physiological responses including tympanic temperature, skin temperature, and heart rate, along with perceptual measures such as thermal sensation and perceived exertion, were assessed. The results showed that both the PCV and ICE interventions effectively reduced heat strain, although they had different effects. PCV cooling effectively reduces physiological and perceptual strains immediately after physical exertion; however, this effect does not last in the recovery phase. In contrast, ICE ingestion reliably lessens physiological and perceptual strains throughout the activity and recovery periods, substantially impacting both physical strain and the perception of effort. These findings highlight the significance of ICE ingestion as an effective strategy for enhancing worker health and safety in demanding thermal environments.

The ecotourism environment must be kept clean and sustainable for the sake of sustainability and comfort of visitors. Bukit Kebo Tourism Area is one of the many ecotourism and edutourism destinations in Balikpapan City. With the increasing number of visitors (tourists) to Bukit Kebo, it has an impact on the increase in the volume of waste produced. The increase in the volume of waste has not been managed properly, because the waste is only piled up and burned. Where the impact of hoarding can provide the potential for environmental pollution and the results of burning waste also cause pollution. In overcoming these problems, a solution is offered by using the concept of a waste bank to manage waste, as well as providing assistance to partners about the importance of recycling waste. In addition, education is also carried out for visitors to increase awareness and attention about the importance of maintaining environmental cleanliness through the installation of appeal plaques and campaigns through the distribution of brochures. The results of the responses given by management partners and visitors show quite positive results regarding the impacts given from the results of activities to always maintain environmental sustainability and cleanliness, especially in tourist areas.

PT SPPA is a company that deals with the repair of mining components or heavy equipment. The company serves repairs and inspections of various types of machines, such as generators, welding machines, compressors, water pumps, and tractors. The fabrication department needs improvement in terms of structuring the work environment, especially in the toolkit area. The fabrication department is a part of the company which in carrying out its duties includes fabrication works such as material surface smoothing, component welding, the process of unification between parts in an item. In the area where the toolkit is located, it can be seen that the area is not well-organized, such as a hose that is not properly coiled, equipment collected on a large scale, and also there are still some unused items that give the impression of filling the space area of the toolkit. Therefore, a proposal for improvement is made using the 5S method, namely Seiri, Seiton, Seiso, Seiketsu, Shitsuke or can be interpreted as Concise, Neat, Clean, Treat, Diligent. This method can be used to produce a higher quality work area related to these five aspects, so as to reduce or eliminate the time to look for equipment in it. Then, suggestions for improvements through 3D designs are also generated based on previous evaluations regarding the similarity of item functions.
